Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 271,682,375, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 271,682,375 | |
| -1 | -271,682,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,682,375.
Example:
1 x 271,682,375 = 271,682,375
and
-1 x -271,682,375 = 271,682,375
Notice both answers equal 271,682,375
With that explanation out of the way, let's continue. Next, we take the number 271,682,375 and divide it by 2:
271,682,375 ÷ 2 = 135,841,187.5
If the quotient is a whole number, then 2 and 135,841,187.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 271,682,375 | |
| -1 | -271,682,375 |
Now, we try dividing 271,682,375 by 3:
271,682,375 ÷ 3 = 90,560,791.6667
If the quotient is a whole number, then 3 and 90,560,791.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 271,682,375 | |
| -1 | -271,682,375 |
Let's try dividing by 4:
271,682,375 ÷ 4 = 67,920,593.75
If the quotient is a whole number, then 4 and 67,920,593.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 271,682,375 | |
| -1 | 271,682,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 1,373 | 1,583 | 6,865 | 7,915 | 34,325 | 39,575 | 171,625 | 197,875 | 2,173,459 | 10,867,295 | 54,336,475 | 271,682,375 |
| -1 | -5 | -25 | -125 | -1,373 | -1,583 | -6,865 | -7,915 | -34,325 | -39,575 | -171,625 | -197,875 | -2,173,459 | -10,867,295 | -54,336,475 | -271,682,375 |
